12:40pm Heavy Rains - visibility less than 100m - very dark sky - feels like 7pm

2pm continous downpour - strong wind felt

4pm flooded roads: Acacia St (1 foot at deepest point) immediately after Otero Ex. - Rescue operatives from Brgy Sta. Rita already on standby at this site.

Filtration Road (approx 1 foot deep between Mayumi St and Santos Store) barely passable to light vehicles.

In Elicano Street East Bajac Bajac, traffic enforcer reported that light vehicles are diverted to Rizal Ave. to prevent road blockage due to stalled vehicles.

Mabayuan river in critical level, you can notice very strong current and water level almost reaching road level when driving at Acacia Road.

Precipitation report for Olongapo City from www.weather-forecast.com

Saturday Afternoon - 37mm

Saturday Evening - 36mm - low lying and flood prone areas are warned of the high probability of flooding.

It can be recalled that in previous flooding, precipitation report are between 38 and 40mm

While there are reports that Pepeng is on its way out (storm signal covering Zambales lifted) and that Olongapo City is now said to be safe, being prepared and cautious is still the best way to go.

Heavy rain (total 100mm), heaviest during Sat afternoon (36mm) forecast from www.weather-forecast.com means that we should expect considerable rainfall, while flooding will not be the same as last weeks, possibility of landslides exists due to the already soaked ridges.

NASA's Tropical Rainfall Measuring Mission satellite (TRMM), a joint mission between NASA and the Japanese space agency JAXA, captured an image of Parma's rains already affecting the Philippines on October 2 at 00:43 UTC, 8:43 a.m. local Manila Time (8:43 p.m. EDT, Oct. 1). TRMM noticed that most of the rainfall around Parma's center is between 20 and 40 millimeters (.78 to 1.57 inches) per hour.

Typhoon Parma is a huge storm and NASA's TRMM satellite sees it is already bringing more unwanted rains and gusty winds to the typhoon-weary and devastated Philippines. Parma, also called "Pepeng" in the Philippines, will bring heavy rains there today and tomorrow before moving back to sea.

This writer specially likes the NASA TRMM because is gives visuals and readily understandable predictions specially with regards to rainfall and precipitations. These data are important that I could not see the reason why it is not being fully utilized by our local weathermen, this representation not being a professional weather forecaster was able to warn our constituents of the impending flooding by simply using information readily available in the net. (see sample image below when massive flooding in Luzon was predicted.)

Below data is from PAGASA for comparison
